The settings here are important.

​

When it comes to performance see the file saving options.

​

raw options are under 'File Compatibility'

​

The rest are also interesting as you can make PS CC ignore EXIF and Meta data information.  I am not sure why one would do that but then again, it is just me.

​

Disable PSD and PSB compression.  This may have compliance issues with other software, I do not know.

​

Maximize compatibility?  Your choice, I say no.

​

Recent list of file open, well...  'Blah'  it takes some memory away but very little.  I set it to 10.

​

Enable Adobe drive?  Heck no!  This allows you to store your files on the cloud.  All well and good but you need a high speed connection for this to be efficient.
